Including Dynamic Line Rating into the Optimal Planning of Distributed Energy Resources

• Dynamic line rating (DLR) is an emerging technology that can remove strict power transmission constraints and potentially reduce investment costs in new generation technologies in microgrid.By implementing dynamic rating into distributed generation sizing and placement problem, it is possible to reduce the investment costs on new distributed energy resources by achieving improved optimal power flow results as compared to planning without considering DLR.This paper explores the possibility of complementing a model for optimal sitting and placement of the distributed energy resources in microgrids, which has been developed at Berkeley Lab with the dynamic line rating. The comparison of results between a solution with no DLR and solution with DLR has shown a decrease in investment costs as well as reduced number of installed generators.
